Specification of Letters Patent.

Patented Aug; 2,

Application filed November 3, 1917. Serial No. 200,001. I

To all whom it may concern:

Be it known that I, FRANK A. DECKER, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Sanitary Devices, of which the following is a specification, reference being had to the accompanying drawings, illustrative of one particular embodiment of my invention.

Among the objects of my invention are to provide a simple, inexpensive, easily operated and efficient disinfecting and deodorizing apparatus, and in articular to provide in such apparatus a evice having these advantages and which can be easily filled and which will with certainty and simplicity deliver a measured quantity of concentrated disinfectant liquid predetermined, for proper disinfecting of a predetermined amount of water, and to produce a proper mixture. Also to simultaneously provide deodorizing apparatus; and to produce such a device that can be readily installed in conjunction with the other parts of the apparatus and be adapted for manual and intermittent operation when desired, so as to provide a most simple, eflicient and sanitary apparatus.

In the particular embodiments shown in the accompanying drawings forming a part hereof:

Figure 1 illustrates a preferred form of the reservoir and supply device in vertical section.

Fig. 2 is an elevation showing an installation of the apparatus.

Fig. 3 is a modified installation, in elevation, with fragmentary section.

Fig. 4 is an elevation, with fragmentary section, of a supply reservoir with details modified.

Fig. 4 is a section of a detail applicable to the form shown in Fig. 4.

Fig. 5 is a fragmentary view of the upper bend of a supply pipe modified in detail, in part section.

As shown, A is a reservoir for disinfectant with means for measuring and forcing a measured supply of disinfectant through a system. B is a supply ipe leading from the reservoir to the vessel 8 containing water to be disinfected, which, as shown in Fig. 2, leads from the reservoir to a lower level, and in Fig. 3 the disinfectant is forced from a lower level to a higher level fordelivery'of the charge. i i

In Fig. l the reservoir and pump A has the supply pipe B leading outside the cyllnder of the reservoir, in which case suitable means is shown for injecting-or spraying a predetermined portion "of: the disinfectant into the top of the reservoir, and in "modified form is shown in Fig. 4.

The reservoir and supply'pump comprise a cylinder D and detachable lower" cap E, into which issecureda pump barrel F with openings G on the inner side of the head E of the cap E. The'plunger H fits the pump barrel F and is operated by apist'onrod H, which passesthrough theguide h, which supports the spring J held between said gulde and support It and an adjustable collar 7', on the piston rod. Near the top the piston rod has another adjustable collar 7", which limits the upward movement ofthe piston rod-to preventthe pistonEfrom-being pulled out of the barrel. This collar j" engages a guide box7c in a cap K detachably securedto the top of the cylinder D,scre.wed on 'or otherwise detachably held as by "a collar K. The member K is bowled and hasperforations is and on the interior of the cylinder near the top, preferably in'close proximity to these openings, af'wiclr orfabric L is secured. Y I

The tube B has a section I). leading from the bottom of the pump barrel through the lower cap E to a bend b at the top, and turns downward inside'fof the cylinder D, as at b, and leavesthereservoir' againat the bottom. In the bend b" there are orificesM-M. 1

Where the supply tube 6 leaves the reservoir a coupling N surrounds it and provides for the junction of an outside section of the tube b.j This coupling sleeve. N may be a part of the supporting bracket 0, adapted to be held to the wall or other Sta tionary member by screws 79-79, and having its upper end engaging the cylinder ,by a slip joint under the strap P; The exit end of the supply pipe Bvis provided with a spray nozzle Q. 1 j p In the form shown in Fig. Al the supply pipe leaves the bottom of the pump barrel and e-xtends upward on the outside ofv the cylinder D, and near the top an offsetR is provided with an orifice 7- leading into the top "of the cylinder 1), while *a coupling sleeve S, suitably secured to the top of A,

Erovides for joining the supply pipe section with such further pipe connections as may be desired. In Fig. 4 the outside pipe Bis indicated in the form in which the topbend of a siphon arrangement of the piping is' "Asshownin Fig. 5, a small valveT may be provided, having a lateral pipe Rf with an orifice 1" leading into'the top of the cylinderA.

It will thus be seen that in the particular form of embodiment ofvmy invention which I have illustrated and specifically described, the reservoir A-can be readily filled by anyone, without additional devices, by pouring the concentrated disinfectant, into the top, and by pressure on'the knob at the top of the piston rod a predetermined amount of the contained liquid is projected through the tubing to the finalorifice Q, where it is spra ed into a non-portable receptacle containing water, with which it mixes formingthe necessary disinfecting mixture- In passing through the bend b of the tube, the passage of the liquid down the side 6'. and beyond, in the arrangement shown in Fig. 2, would constitute a siphon tending to draw a continuous stream of the liquid out of'the reservoir, but this is prevented .by the small openings MM near the. top of the bend, the size of which openings is made smaller than the section f theinterior of thetubing 6, so that only a portion of theliquid projected through the tubing is emitted from these small openings M,which, however, will break the siphon and permit the predetermined amount of liquid that has passed the top of the bend, to flow through the balance of the tube to the exit where it 'mingles; with the water, .while on the up.-

ward leg ofthe bent tube the liquid will settle back and find its level with thegmain body of liquid in the reservoir, leaving'the device immediately ready for the next use.

The orifices at the. top of the bend are so arranged-"that the fractional portion of the liquid emitted from themis projected about the top of the cylinder D, on the inside, and particularly to impinge upon the fabric L, thereby moisteningthe fabric with the concentrated. disinfectant thus providing for evaporation toa predetermined extent, as desired, for the purpose of efl'ectingdeodorizing, The amount of liquid so sprayed into the top of. the reservoir is more than suflicient for deodorizing purposes and-:passes through the-air in the top of the reservoir and falls back to the mainbody of the liq: uid,:thereby eflecting a. circulation of the liquid upon each operation ofthe device,

which circulation is of sufiicient extent to keep the liquid properly mixed and uniform ii -strength I j v p i .The collar 7" onithepiston rod'HQis'so arranged that when the cap Kisinfiposit on the piston rodcannot rise b yond, a

point which would allow the piston H to pass out of its proper positionat the top of The spring J can be adjusted as to tension, by the collar j, with a ,setscrew, but if desired the springmay be made longer and engage the stop collar j.

when the liquid passes through thetube, and which thereafter opens quickly to admlt ample air to break the siphon.

As shown in Fig. 3 the device'is set-into the floor, and the supply pipe leads from it upward through the base plate on the floor,

properlyprotecting the tube which passes up to and over the edge of the reservoir containing water to be disinfected. In this case thearrangemen'tc for atomizing and deodorizing, as shown in Fig. 5, could be used,

and the proper proportion of pump capacity isarranged to deliver the desired quantity of concentrated disinfectantat the final orifice, irrespective of what might be siphoned back to the reservoir or fall back through the vertical leg of the pipe. V v

The supporting-"device, as shown in -Fig. 1, may be a strap secured to a wall or other object by screws, with which it remains permanent "and the reservoir A is then adjusted to it by insertingthe end of the pipe 6, projectingat the bottom, into 'the coupling N, atthe same time that the top of the bracket 0 slides into the clip or joint P, on the cylinder D.

' Thus in the preferred form-mydevicei is a complete, self-contained reservoir embodying means for delivering in measured quantity of concentrated'liquid in .therequired, predetermined amount, to the water tobe disinfected, and at'the same time spray a portion of the'liquid in a manner that will effectually deodorize, and at the same time will circulate the liquid in a desired mam ner, while all of the parts. are inclosed and cooperate in amanner that avoids complication, or any liability to breakage or interruption of: operation. .It lends itself particularly t'oop'erationby anyone in the simplest possible manner, and in all is simple and cheap to. manufacture, and requires no skill to replenish or keep in service.

While various modifications may be made in arrangement and in the construction of parts and in the material usedin the manufacture of the device, it will be understood 1 do not limit myself to the particular: form or forms herein shown and described,- but what Iiclaiin and desire to secure by Letters Patent is: r

-1. A disinfectant apparatus comprising a disinfectant reservoir, openings to charge the 'Same, means for circulating disinfectant therein and aerating means actuated by the circulation of said liquid and means to dif-- fuse the disinfectant vapor through the top of the reservoir and connections for delivering a measured quantity of said liquid exterior to said reservoir.
